AMP1CSR – Amplifier 1 Control and Status register
Table 21-9.
Bit
Read/Write
Initial Value
• Bit 7 – AMP1EN: Amplifier 1 Enable Bit
Set this bit to enable the Amplifier 1.
Clear this bit to disable the Amplifier 1.
Clearing this bit while a conversion is running will take effect at the end of the conversion.
Warning: Always clear AMP1TS0:1 when clearing AMP1EN.
• Bit 6 – AMP1IS: Amplifier 1 Input Shunt
Set this bit to short-circuit the Amplifier 1 input.
Clear this bit to normally use the Amplifier 1.
• Bit 5:4 – AMP1G[1:0]: Amplifier 1 Gain Selection Bits
These 2 bits determine the gain of the amplifier 1.
The different setting are shown in
Table 21-10. Amplifier 1 Gain Selection
To ensure an accurate result, after the gain value has been changed, the amplifier input needs
to have a quite stable input value during at least 4 Amplifier synchronization clock periods.
